Blitz part 2 shelf life ?

[CONSOLE_BUTCHER]

I have a bottle of part 2 that has been mixed to the proper ratio and it has been sat for a year. How much longer will it last before becoming unusable or is it unusable?

I'd assumed this was designed to be added to the loop directly so interested to see what people say. @Mayhems what's the official word?

It cant be added to the loop directly, its needed to mix 25ml part 2 with 975ml water. There is a litre of total liquid and most loops although they dont look like it, dont actually use a lot of water. Maybe a quarter to a half litre of liquid.
